The PE-3 is a single circuit board that is connected directly to the RI-300 auxiliary buss to add 3 link ports to the controller.  In addition, you can plug up to 2 PE-3s on the auxiliary buss, adding a total of 6 link ports to 1 or 2 controllers.

The PE-3 supports 3 identical full duplex link ports.  This means that any port can be configured to output and input audio at the same time.  The only limits to the PE-3’s audio routing is that you cannot repeat audio on a port and you cannot connect ports together on the PE-3.  The PE-3 can also support various remote base options.  Any or all ports can be connected to the Doug Hall RBI-1 or the Pacific Research FTL-RBI.
